Raytheon uses integrated circuit technologies in RF applications, many of which require extremely small footprints. A large portion of an integrated circuits' performance is achieved through the use of passive elements which can also be quite large. The use of ferromagnetic inks is a promising area of opportunity for decreasing the area occupied by these elements. The 2016-17 Raytheon team identified magnetic materials and additive manufacturing processes that Raytheon could integrate into existing microwave board circuitry.
